[0020] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a construction waste air separation device includes an air separation box 1. A support frame 2 is fixedly connected to the bottom of the air separation box 1. A heavy object discharge port 7 is opened at the bottom of the air separation box 1. A feeding box 6 is fixedly installed at the top of the air separation box 1. An air inlet window 3 and a discharge box 5 are fixedly installed on the front and rear sides of the air separation box 1, respectively. The interiors of the feeding box 6, the air inlet window 3, and the discharge box 5 are all in communication with the interior of the air separation box 1. A blower 4 is fixedly installed inside the air inlet window 3. A light object discharge port 8 is opened at the bottom of the discharge box 5. The interior of the feeding box 6 is provided with a working... The dispersion mechanism for construction waste consists of multiple first dispersion rollers 10 and multiple second dispersion rollers 11. Both ends of the multiple first dispersion rollers 10 and multiple second dispersion rollers 11 are rotatably connected to the two inner walls of the feed box 6. The multiple first dispersion rollers 10 and multiple second dispersion rollers 11 are arranged in a horizontal linear array. The first dispersion rollers 10 are located below the second dispersion rollers 11. The multiple first dispersion rollers 10 and multiple second dispersion rollers 11 are staggered. The outer wall of the feed box 6 is provided with a drive mechanism that acts on the first dispersion rollers 10 and the second dispersion rollers 11.

[0021] The drive mechanism consists of a first transmission component, a second transmission component, and a third transmission component. The first transmission component acts on multiple first material distribution rollers 10, the second transmission component acts on multiple second material distribution rollers 11, and the first material distribution rollers 10 and the second material distribution rollers 11 are transmitted to each other through the third transmission component.

[0022] The first transmission assembly consists of a motor 13 and a first gear 16. The motor 13 is fixedly installed on the outer wall of the feed box 6. The output shaft of the motor 13 is fixedly connected to the first material roller 10. The ends of the multiple first material rollers 10 away from the motor 13 all penetrate the side wall of the feed box 6 and extend to the outside of the feed box 6. The extended ends of the multiple first material rollers 10 are all fixedly fitted with the first gear 16, and two adjacent first gears 16 mesh with each other.

[0023] Connect an external power source to motor 13, start motor 13, and drive one of the first material rollers 10 to rotate. Under the action of multiple first gears 16, the remaining first material rollers 10 will also start to rotate.

[0024] The second transmission assembly includes a second gear 17. The ends of multiple second material rollers 11 away from the motor 13 all penetrate the side wall of the feed box 6 and extend to the outside of the feed box 6. The extended ends of multiple second material rollers 11 are all fixedly fitted with the second gear 17, and adjacent two second gears 17 mesh with each other.

[0025] When one of the second material distribution rollers 11 rotates, the remaining second material distribution rollers 11 will also start to rotate under the transmission action of multiple second gears 17.

[0026] The third transmission assembly consists of a transmission wheel 14 and a transmission belt 15. One first material roller 10 and one second material roller 11 have their ends near the motor 13 penetrating the side wall of the feed box 6 and extending to the outside of the feed box 6. The extended ends of the first material roller 10 and the second material roller 11 are fixedly fitted with transmission wheels 14. The transmission belt 15 is wound around the outside of the two transmission wheels 14. The transmission belt 15 and the transmission wheels 14 are compatible with each other.

[0027] When the first material roller 10 rotates, it will drive a transmission wheel 14 to rotate. Under the action of the transmission belt 15, the other transmission wheel 14 will rotate synchronously, thereby driving the second material roller 11 to rotate.

[0028] Multiple material feeding rods 12 are fixedly installed on the outer walls of the first material feeding roller 10 and the second material feeding roller 11.

[0029] Among them, protective boxes 9 are fixedly installed on both sides of the feed box 6, and the drive mechanism is located inside the protective box 9.

[0030] The protective box 9 can protect the drive mechanism.

[0031] It should be noted that the protective box 9 located outside the motor 13 is equipped with heat dissipation holes and through holes for installing external wires, which are not shown in the figure.

[0032] This utility model provides a construction waste air separation device, the specific working principle of which is as follows:

[0033] During use, construction waste is fed into the feed box 6 by the conveyor. After the construction waste enters the air separator 1, the blower 4 is started. The strong wind blown by the blower 4 blows the light waste, such as paper scraps and weeds, into the discharge box 5 and out through the light waste discharge port 8. The heavy waste, such as cement, stones and iron blocks, is discharged from the heavy waste discharge port 7 at the bottom of the air separator 1, thus completing the air separation of construction waste. The staff only needs to set up collection devices at the light waste discharge port 8 and the heavy waste discharge port 7 respectively to collect the light waste and the heavy waste respectively.

[0034] Among them, blower 4 is model TMM-100;

[0035] When the waste enters the feed box 6, the multiple first scattering rollers 10 and multiple second scattering rollers 11, which are distributed in an alternating manner, can disperse the waste and prevent the construction waste from being too concentrated when it falls, thus resulting in poor air separation effect. The drive mechanism will drive the first scattering rollers 10 and the second scattering rollers 11 to rotate. With the help of the material pusher rods 12 on the scattering rollers, the construction waste can be prevented from clogging the scattering rollers.

[0036] It is important to note that construction waste undergoes pretreatment before air separation, typically involving the following two steps:

[0037] The first step is classification and sorting: First, remove excessively large construction waste, such as large pieces of concrete, wood, and metal, manually or mechanically to avoid clogging the air separation equipment. At the same time, try to preliminarily classify the construction waste according to its material to reduce interference from impurities.

[0038] The second step is crushing and screening: the construction waste is crushed to a suitable particle size (usually within a few centimeters) by a crusher, and then screened to remove excessively fine dust and excessively large particles, so that the material particle size is uniform and the airflow can better separate substances of different densities during air classification.

[0039] Therefore, there is no need to worry about large construction debris getting stuck in the gaps between the material rollers.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
